Hi all

There are several `Back door` for student on internet which are really specific more than 8051 topic.

For hint on electronic-base question,it`s often needed for 8051 project but as I`ve ever seen on this web board.There are always topic about h/w concern.

For my opinion,H/W implementation is neccessary to be said here but there is no need to push it to a new corner.

I still a little bit don`t understand Gil`s idea.
Is this?

topic: key board and 8051

H/W implement which could be place in 8051 forum.

topic: How to firing Triac

This is real electronic and should be in electronic corner ,Right?

If this is your idea,I think we face a problem about how concern of topic to 8051.
Or may be you really don`t need to concern?

Best Regards
